Hi everyone!

Can't seem to find an answer to my doubt, so I decided to post the question  
and see if someone can help me.

In my application, I have an array of ids which comes from the backend and  
which is ordered already as I want, for example: [0] =\> 23, [1] =\> 12, [2]  
=\> 45, [3] =\> 21

I then "ask" elasticsearch the information corresponding to each id present  
in this array, using a terms filter. The problem is the results don't come  
in the order of the ids I sent, so the results get mixed up, like: [0] =\>  
21, [1] =\> 45, [2] =\> 23, [3] =\> 12

Note that I can't sort in elasticsearch by the sorting that orders the  
array in the backend.

I also can't order them in php as I'm retrieving paginated results from  
elasticsearch, so if each page had 2 results, elasticsearch could give me  
the info only for [0] =\> 21, [1] =\> 45, so I can't even order them with php.

How can I get the results ordered by the input array? Any ideas?

Thanks in advance
